Generally, hemoglobin’s (Hb) measurement uses invasive methods, but it has several disadvantages, such as in time efficiency and it is not friendly to those who are afraid of needles. Recently, there were many researches who have been done to measure Hb with non-invasive methods with different techniques. Pulse oximetry, diffuse reflectance spectroscopy, photoplethysmograph, and digital photography with image processing are Hb level measurement techniques with non-invasive methods. This research aims to construct the Hb level measurement instrument called AUHb using laser with non-invasive methods. It adopted Beer-Lambert law on spectroscopy, using laser as a light source and photodetector as an optical sensor that captures intensities of light through blood samples. This technique was done by taking blood samples from the volunteers who measured by HAMA and also measured by AUHb. Both of the measurment results were used as conditional constrain to determine mathematical models as a transfer function between light intensity that captured by photodetector and Hb level. The volunteers consisted of male and female aged between 20–40 years old. The created AUHb has 91% acuracy rate and could be used by public.
